Follow these steps carefully
Remove all items from the glovebox on the Cadillac CTS-V and open it fully. Slide the passenger seat rearward for knee room and confirm the replacement filter matches the old one before disassembly.
Press both sides of the glovebox inward to bypass the stop tabs and swing it down past its normal open position. The rectangular filter door on the HVAC case is now exposed.
Release the clips holding the rectangular filter door and pull it off the housing. The rectangular filter door's clips release with a firm pull; keep the door flat when you set it down so its tabs do not bend.
My shop habit: The rectangular filter door's clips release with a firm pull; keep the door flat when you set it down so its tabs do not bend.
Slide the old filter straight out, keeping it level so trapped debris does not spill into the housing. Vacuum the empty slot to remove dust and any foam particles from the old filter's edges. Insert the new filter with its airflow arrow matching the original direction, pushing it fully home so it seals against the housing. Vacuum the slot with a crevice tool — the CTS-V's deep dash makes the slot a dust trap, and a shop vac reaches what a rag cannot.
Snap the filter door back on until its clips engage, then raise the glovebox past its stop tabs and reconnect the damper arm on the right side. Close the glovebox and check that the latch catches smoothly. Start the 2011-2014 CTS-V and run the HVAC on high to confirm quiet, strong airflow from all vents with no rattles from a loose filter door. Snap the door back on until you hear both clips engage; a door held by one clip will rattle over bumps.
This is the part I see people get wrong: I snap the door on until both clips engage — I've had a one-clip door rattle over bumps.
Before installing the new filter, vacuum the empty housing slot thoroughly to remove dust, foam particles, and debris left by the old element. A clean housing keeps the new filter from immediately picking up old contaminants. Wipe the filter door's seal with a damp rag so it closes tight against the housing for a proper seal. Wipe the door seal with a damp rag, not a dry one — a damp wipe lifts the fine dust that prevents a tight seal.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
